KUSCPGR-BB, 240-33 Ohm, Electric Holding Tank Level Gauge, 12V / 24V, 2" (52mm) with Backlight

I have now installed (5) senders and gauges in my boat ((1) water tank, (2) holding tank & (2) fuel tanks). All of the gauges and senders are made by KUS. The wiring instructions are straight forward and easy to follow, and all of the pieces worked properly. There appeared to be no flaws in manufacturing. I would, however, recommend always checking the impedance of senders before installing them. If you don't have an olm meter, simply put the whole system together with a small (12) volt battery and test the sender by sliding the float up and down while watching the gauge.
